CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 396,919, dated January29, 1889.

7 Application filed October 12, 1888. Serial No. 287,894. (No model.)

To (LZZ whom it may concern:

Be it known that we, JOSEPH D. CAEL and GRAHAM L. Ocmnboth citizens ofthe United States, and residents of Vilmington, New Castle county,Delaware, have invented cer tain Improvements in Uar-Couplin gs, ofwhich the following is a specification.

The object of our invention is to construct a simple and easily-operatedcar-coupling of the interlocking-hook type, and this obj ect we attainin the manner hereinafter set forth, reference being had to theaccompanying drawings, in which Figure 1 is a sectional plan viewshowing the two coupling-heads coupled. Fig. 2 is a side view of theimproved coupling. Fig. 3 is a diagram view showing the heads in the actof uncoupling. Fig. 4c is a diagram view showing them in the act ofcoupling, and Figs. 5 and (5 are views of modified forms ofcoupling-hook for the head.

A is the coupling-head, made either In the form of a casting in onepiece or formed of wrought-metal plates secured together in any suitablemanner. In the drawings we have shown the head composed of wrought-metalplates separated by filling-pieces b b, so to form a recess or slot, a,between the plates, the recess extending into the filling-piece Z), asshown at a. In the upper and lower plates are slots 0 c, one near theinner end of the coupling-head and the other near the outer end of thesame. In the recess Ct is a coupling-hook, D, Fig. 1, this coupling-hookhaving a head, (Z, which engages with the head of the hook carried bythe opposite couplinghead. The hook D is tapered toward its point (1 forthe same purpose as in other couplings of this class.

From the body of the hook D project pins g g, the ends of which arecontained in the slots 0 c in the upper and lower plates of the couplinghead. Near the rear of the couplinghook D, on the inner side, is aprojection, 6, between which and the hook-head (l is formed a recess, f,for the reception of the hook of the opposite coupling-head. Thisprojection e is wider than the shank of the hook, being in fact as wideas the depth of the couplinghead or of the head (I of the hook, so that,as the opposite hook approaches, its end d strikes the projection e, asshown in Fig. 4:,

thus forcing the hook in the direction of its arrow and coupling theheads together, as more fully described hereinafter.

In the outer face of the hook D is a recess, forming a shoulder, 2', andpivoted .atj in the recess a, directly back of the portion Z) of thecoupling-head, is a dog, E, which is held against the outer face of thecoupling-hook D and caused to engage with the shoulder e' by a spring,F, attached to a pin, 71., on. the head. Connected to the dog E is achain, it, which can be led to any convenient portion of the car, or maybe attached to a lever, as circumstances suggest, so that the dog can bewithdrawn without the necessity of the brake-- man going between thecars. A pin, 1), is placed at the back of the spring F for the purposeof stiffening the spring and preventing undue outward movement of thedeg F.

The slot 0' is curved transversely, so that the outer portion of thehook will swing transversely on the forward movement of the hook, andthe slot 0 is inclined slightly in the opposite direction, whereby whenthe dog releases the hook and there is an outward pull upon the latterit will be moved in the direction of its arrow, Fig. 3, the outerportion of the hook swinging transversely, so that a combined forwardand transverse movement is obtained,

thus uncoupling the hooks of the two heads.

I prefer to form projections (Z on the heads of each of the hooks D, theobject of these projections being to prevent the accidental transverseseparation of the heads, thus overcoming all risk of uncoupling, exceptthat due to the forward movement of the hook.

\Vhen it is desired to couple the cars, the retaining-dog of one of thehooks is withdrawn, allowing the hook to assume the position shown inFig. 4. hen the opposite coupling-hook comes in contact with the projection e of the loose hook, as shown in Fig. 4, it forces the said loosehook backward, and consequently causes the front portion of the hook tobe moved transversely toward the opposing hook, so as to engagetherewith, and as the opposing hook still pushes upon the loose hook itwill finally cause said loose hook to assume such position that the dogE can snap into position, as in Fig. 1, thus locking the hook securelyin place and coupling the two heads.

To release the coupling, the dog of one or 'other of the couplings ismoved out of engagement with the hook D, so that on the separation ofthe coupling-heads, as shown in Fig. 3, the head of the stationary hookwill force the head of the loose hook transversely out of engagementwith it and thus effect the uncoupling, the loose hook then being inposition to be recoupled at any time.

lVhen the parts are in the position shown in Figs. 3 and 4, the pressureof the dog E upon the coupling-hook will keep said hook in thetransversely-extended position, unless the hook is pushed inintentionally.

The hooks shown in Figs. 1, 2, 3, and 4 are intended for coupling notonly with like hooks, but with hooks of the Miller type, while the hookshown in Fig. 5 is the preferred form of hook when the cars are equippedsolely with our improved coupling-heads, Fig. 6 showing the form ofeoupling-hook used in connection. with hooks of the J anney type; but itwill be understood that the form of the hook may be altered withoutdeparting from our invention.

The hook D has a heel, w, which, when the heads are coupled, bearsagainst the fillingpieee Z) of the head and serves to relieve the pins gof the strain due to bumping or lateral thrust upon the hooks.

Instead of forming slots in the top and bottom of the coupling-head,pins may besecured to the heads and slots formed in the couplinghooks,the result being the same.

Each coupling-hook is provided with a slot, .9, for the reception of alink, and an orifice, t, for the insertion of the usual coupling-pin, soas to permit coupling with ordinary cars by link and pin.

We claim as our invention.

1. The combination, in a ear-coupling, of the head, a coupling-hook, anda retainer therefor, with longitudinal and transverse guides for saidhook, by which the hook will have a combined longitudinal and transversemovement on its release from the retainer, substantially as described.

2. The combination, in a car-coupling, of the recessed head having slotstherein, as described, with a coupling-hook having pins adapted to saidslots, and a spring-dog en ing with the outer face of saidcoupling-hook, substantially as described.

3. The combination, in a car-coupling, of the coupling-head, the slidinghook having a head, d, and an extension or projection, 6, forming withthe head a recess, f, for receivingthe hook of the opposing head and aretainer for said hook, substantially as specified.

4. The combination, in a car-coupling, of the head, with a hook, andlongitudinal and transverse guides for said hook, with a projecting lug,(Z on the engaging-head of said hook, substantially as and for thepurpose set forth.

5. The combination, in a car-coupling, of the recessed head havinglongitudinal slots 0 at the rear and transverse curved slots 0 at theouter end, with a coupling-hook having pins working in said slots,substantially as described.

6. The combination of the slotted couplinghead, the locking-dog, and thecoupling-hook having pins adapted to the slots in the head, and having aheel bearing against an abutment in the head and serving to relieve thepins from strain, all substantially as specified.

'7. The combination of the couplinghead, its hook, the swinginglocking-dog, the spring acting thereon, and a pin acting as a backingfor the spring and as a stop for the outward.

movement of the dog, all substantially as specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
